It hit the wall for me when it demonstrated that it took the Lebor Gabála Érenn's Milesian invasion narrative literally.

Also when it fitted Crom Crúaich and Herakles into the same universalising schema by claiming that they were entirely alike. HELLO GRAVESY WE DON'T ACTUALLY KNOW MUCH AT ALL ABOUT CROM CRÚAICH.

I expect my review will be entertaining but will not satisfy any Gravesians or THIS IS TRUE neopagans.
